. W SHING-MACHINE.

, Specification of Letters Batenti Patented Nov. 21, 1916.

Application filed 0ctober23, 1915. Serial No. 57,390.

To all whom it may concern:

Be it known that I, ABRAHAMTRAUBE, a citizen of the United States, and aresident of New York, borough of Brooklyn, in the county of Kings andState of New York, have invented certain new and useful Improvements inWashing-Machines, of which the following is a specification.

This invention relates to washing machines such as are used in drycleaning establishments, utilizlng an inflammable port it. However, theflame as it issues from the tub very often is carried by a draft to someopen vat containing gasolene or other inflammable liquid setting thesame on fire with disastrous results.

The object of the prevent invention is to provide means whereby theflame as it issues from the tub is confined and prevented from beingacted on by drafts, thereby rendering the same harmless. In carrying outmy invention, I provide a novel combination of parts whereby this resultmay be accom- -plished in the most simple and efiicient manner.

In the drawings illustrating this invention, Figure 1 is a frontelevation of a washing machine with my.- invention applied "thereto,Fig. 2 is an end elevation of the machine'and Fig. 3 is a-section takenalong line 83 of Fig.1. I

Referring in detail to the drawings, the washing machine consists of atub 10, having a movable element therein driven by suitable gearinginclosed in a gear casing 11. The cover 12 of the tub is hinged uponsuitable hing'es l3 and this cover is open for the insertion of thecontents of the tub. When the materialis placedin the tub for thecleansing operation, the cover 12 is clamped by any suitable means toprevent. the same springing open when the explosion takes place. Thisclamping device may be a number of U clamps 14, attached to the frame ofthe tub by suitable chains 15, and engaging the front flange 17 of thecover by means of a set screw 18 which holds this flange against anangle iron 19. These clamps may be disposed at anumber of places alongthe flange 17 as at each end and at mid-length.

To provide a relief vent for the burnin gases when an explosion takesplace, I pr? vide an-auxiliary cover or lid 20 at the rear of the tub.This lid is also hinged on the hinge 13 together with the cover 12, butopens from the-rear instead of from the front. Suitable stops consistingof arms 21 attached to the lid 20 serve to limit the opening movement ofthis lid when the same is forced open. This is illustrated clearly indotted lines in Fig. 3. The arms 21 are formed preferably with curvedfaces- 22 conforming in contour to the curvature of the front cover 12.Also the disposition of these arms is such that when the lid 20 is raiseit is substantially vertical, so that it forms a shield whichdirectstheflames upward. At each end of the tub I also provide vertical shields 23which are preferably attached to the wall and to a bracket 24 disposedat each end of the tub.

It willbe seen that between the wall, the

shields- 23. and the lid 20 when the same is opened, the flame isentirely confined to travel in a vertical direction toward the ceilingand is protectedsubstantially from all sides. Thus, when the explosionforces the lid open the flameshoots upward and then when the lid drops,it is put out with absolutely no damage, as the combustion at theinterior of the tub is terminated for lack of oxygen and the exteriorflame is confined where it will do no harm. The center of gravity of thelid 20 when it opens is so disposed that it tends to close the same assoon as the force of the flame has spent itself. Thus the flame isentirely put out automati cally, as the closing of the lid as abovestated prevents the.acoess of oxygen to support the flame. e

It will be obvious, of course, that instead of forming the shields 23 ateach side an ordinary hood may be used in conjunction with the lid 20.This hood or flue may extend clear-through the'ceiling to the atmosphereso as to give free vent to the flame. However, this will be clearwithout the necessity of further description or illustration.

Various other modifications. within the skill of a mechanic may beresorted to Without departing from the spirit of the invention and thescope of theclaims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent: I Q

1., In awashing machine, the combination with, a tub, of a covertherefor, means for locking the cover, an auxiliary cover which is freeto open during the operation of the machine, and means communicatingwith the opening normally closed by the auxiliary cover for confiningthe flame when the' auxiliary. cover is opened by the force of anexplosion. v

2. In a washing machine, the-combination with a tub, of a covertherefor, means for locking the same during the operation of .themachine, an auxiliary cover opening from the rear of'the machine, andmeans at each end of the machine for confining the flame when theauxiliary cover is opened by the force of an explosion.

3. In a washing machine, the combination with a tub, of acover therefor,means for locking the cover, an auxiliary cover which is free to openduring the operation of the machine,stops for said auxiliary cor'er forlimiting the opening movement thereof, and means surrounding the openingnormally closed by the aux liary cover for confining "the: flame whenthe auxiliary cover is opened by the'force ofan explosion 4. In awashing machine, the. combination .with a tub, of a vent thereforconsist ing of a lid which is free to open during the normal operationofthe machine, means for determining the degree of opening of said lidto a vertical position, andsh elds at eachv end of the machine toconfinethe flame to a Vertical direction; a

5. In. alwashing machine, the combination with a tub, of avent thereforcomprising a lid which is free to open during the operation of themachine, and a flue device cooperating with said lid for confining theflame when the'lidv is forced open by an explosion of the vapor withinthe tub.

- (3. In a washing machine, the combination with a tub, of a rentvtherefor comprising a lid which is free to-open during the operation ofthe machine, means whereby the lid wv'hcn open by force of an explosionwithin causes the lid to automatically close when the force of theexplosion is spent, and means for confining the flame when the lidopens.
